On the job, Kari Yau got a call from the local police asking why she was sending a caller multiple adult text messages and sexually explicit emails per day. After further investigation, Karis account records proved the calls were not coming from her phone or email. Neither she nor her mobile company could explain how the messages were sent. After finding no way to block the unsavory messages, she changed her mobile number and quit STI to avoid further embarrassment by association.

For each internal control weakness identified, explain why it is a weakness and recommend a way or ways to correct the weakness.
